A practical nurse is preparing to obtain a capillary blood glucose measurement for a client with diabetes mellitus. In which order should the nurse perform the following actions to ensure an accurate result and reduce the risk of complications? Arrange the steps from first to last.
- 1Verify the client's identity using two approved identifiers.
- 2Cleanse the selected puncture site with an antiseptic swab and allow it to air-dry.
- 3Puncture the side of the fingertip with a sterile lancet.
- 4Wipe away the first drop of blood with a sterile gauze pad.
- 5Touch the tip of the test strip to the second drop of blood.
Answer
The correct sequence is to first verify the client's identity, cleanse the site and allow it to air-dry, puncture the fingertip, wipe away the first drop of blood, and finally apply the second drop of blood to the test strip.
To safely and accurately obtain a capillary blood glucose measurement, the nurse must follow a specific sequence. First, verifying client identity is a mandatory safety standard to prevent errors. Next, cleansing the site and letting it air-dry reduces the risk of infection and prevents chemical interference from the alcohol. Puncturing the lateral aspect of the finger minimizes pain. Wiping away the first drop of blood is a critical step to reduce risk potential, because it contains interstitial fluid and alcohol that can skew results. Finally, testing the newly formed second drop ensures an accurate representation of the client's capillary blood glucose.
